 Baker Hughes Services Add Value for a Venezuela Gravel Pack Project
Baker Hughes demonstrated to an operator in Venezuela how its combined services have added value in the Boscan field. Three different Baker Hughes crews participated recently in a gravel pack project with the implementation of
reaming while drilling (RWD),
wireline logging, and
gravel pack services. Initially, an 8-1/2" hole was drilled and reamed to a 10-1/4" diameter in One Fast Run™ in each of three wells using the Hughes Christensen 10-1/4" RWD eccentric reamer. This operation eliminated the need for two separate operations to drill and then enlarge the hole. During the operation, the Baker Atlas
Wellbore Geometry Instrument tool was used to log these wells. The logs enabled the operator to confirm borehole quality and minimum size required to perform the successful gravel pack operation using the Baker Oil Tools
CS-AP™ and CS-300™ gravel pack systems.

 Directional Casing while Drilling Project for a UK North Sea Well Achieves Performance Milestones
Baker Hughes delivered outstanding Answers while Drilling on its first ever directional
Casing while Drilling (CwD) deployment. This step-change in drilling technology was implemented successfully offshore UK with a 4-3/4" INTEQ
AutoTrak™ bottom hole assembly (BHA) incorporating
CoPilot™ real-time drilling optimization
and the Smart battery system and represents the first casing drilling run worldwide from a
whipstock exit. The BHA was powered by a 4-3/4"
INTEQ
Ultra X-treme™ drilling motor and drilled a total of 933 m (3061 ft) in a single, successful run, building inclination from 39° to 51° and turning from 250° to 205° azimuth. The combined service worked to specification with 100% data recovery and excellent bi-directional communication. This run was also the first-ever deployment where the Smart battery was used to obtain surveys over connections—further increasing drilling efficiency. The CoPilot service provided drilling optimization answers involving weight transmission and hole cleaning, as well as a host of information important for future CwD applications.

 Tank Shark™ Robotic Tank Cleaning System Saves Time and Reduces Confined-Space Exposure
The Tank Shark™ Robotic Tank Cleaning System from the FES (Fluids Environmental Services) group of Baker Hughes Drilling Fluids has achieved more success at its Port Fourchon facility in Lousiana. In February, the offshore supply vessel
Allison arrived at the dock for a mud tank cleaning of barite and other hardened settlement accumulated on her tank bottoms. FES built a lightweight water-based seed mud and installed Tank Shark equipment using the liquid mud plant to help circulate and condition the seed WBM. Only four hours of the 60-hour job were spent rigging up the equipment; 56 hours were spent cleaning, and only six hours of confined-space exposure time were required. Cleaning the tanks only took 2-1/2 days compared to five days for a conventional crew working in a confined space. The Tank Shark system saved the customer $37,000 while speeding turnaround time and improving the efficiency of the overall drilling operation. Also, less material had to be disposed of because the WBM used for this job was fully recovered.

 Baker Hughes Conducts First Straight-Hole Drilling Run in Kazakhstan, Saving $400K
Baker Hughes performed the world’s first straight-hole drilling run in a 12-in. hole in Kazakhstan. The BHA, consisting of the INTEQ 9-1/2"
VertiTrak™ system with 9-1/2"
Xtreme™ motor
and a Hughes Christensen 12"
D Technology PDC bit with
EZSteer™ technology, drilled the 13-3/8" shoe and 1855 m (6086 ft) of formation from 1598 m to 3453 m (5243 ft to 11,329 ft) measured depth. Baker Hughes Drilling Fluids provided a salt-saturated
NEW-DRILLSM PHPA fluid system for the section. The inclination was maintained close to 0.2° over most of the section. Run circulating time was 355 hours (one of the highest ever for a 9-1/2" VertiTrak tool) with a 79% increase in ROP. The PDC
bit was graded in new condition after this record run. The caliper log,
taken after drilling, showed a very smooth in-gauge hole. Close
collaboration between Baker Hughes and client staff saved eight days rig
time and approximately USD 400K for the operator.

 Baker Hughes Installs First Electronically Activated Packer System in Qatar
Baker Hughes has successfully installed the world’s first electronically activated openhole Baker Oil Tools
MPAS-e™ Remote-Set™
packer system with eTrigger™ Technology in Qatar. Some of the world’s most demanding extended reach wells are drilled in this region, which makes interventions cost prohibitive or impossible with existing technology. The operator wanted to isolate sections of the wellbore, but needed to do so without wellbore intervention to actuate the isolation devices. Baker Hughes engineering, manufacturing and supply chain staff worked as a team to incorporate the self-contained electronic package with the reliable MPas™ packer to deliver the solution in less than five months. Both formations in the completion have been tested and show the tools to be positively isolating the two production intervals. The implementation of this new technology greatly reduces the completion cost to the customer.

 Baker Hughes Introduces Mechanical Pipe CutterSM for Downhole Pipe Cutting with Reduced Intervention Risk and Greater Efficiency
Baker Hughes introduced its new Baker Atlas
Mechanical Pipe CutterSM (MPCSM) tool at the 2009 ICoTA Coiled Tubing and Well Intervention Conference in The Woodlands, Texas. The Baker Atlas MPC tool provides precise, downhole pipe cutting, while reducing operating downtime, risk and overall intervention costs. The MPC tool does not use ballistics or hazardous chemicals, which eases logistical and environmental constraint cutting penetration is continuously measured and controlled, allowing cut confirmation and assurance that external tubulars or control lines remain undamaged.

 Baker Hughes ESPs Surpass 1,000 Days Run Time in Offshore Western Australia Field
Four of six coiled tubing-deployed Centrilift
electrical submersible pumping (ESP) systems installed at the Cliffhead Field, offshore western Australia, have surpassed 1,000 days run time. Two of the systems are the only 4" OD coiled tubing-deployed ESP systems in the world. The 1,000 days run time for an ESP is approximately 5,184,000,000 revolutions or the equivalent of your car traveling 70 times continuously around the earth at 3000 rpm with no service!

 New Iron Sulfide Inhibitor Doubles Downhole Pump Run Time and Reduces Treater Upsets
Baker Hughes has developed a new chemical technology for preventing iron sulfide accumulation and deposition in oilfield production systems, filling a technology gap in iron sulfide treatment effectiveness and economics. In a recent application, a three-month field trial of the new Baker Petrolite
iron sulfide inhibitor in a North Dakota production facility more than doubled the run lifetime of the downhole pumps and significantly reduced the treater upsets. This success led the operator to apply this product at the Keene field while also planning to extend this application to the nearby Tioga field.

 Baker Hughes Introduces SureFlo Family of In-well Flow Meters
Baker Hughes has introduced its
SureFlo™ family
of four in-well flow meters that advances differential pressure flow meter technology while conforming to ISO 5167 specifications. The flow meters provide valuable information to enhance hydrocarbon recovery by monitoring water production in order to mitigate the effects of water coning. Continuous real-time flow data also enables operators to track the productivity index to help optimize production. Additionally, permanent downhole flow meters help lower well costs by reducing subsea well test flow lines and reducing or eliminating the need for subsea or surface flow meters. SureFlo meters are providing continuous flow data in several producing and injector wells offshore Nigeria.
